(EASY) How much does the music store charge for a yearly membership?
The music store will charge $5 for a yearly membership.
Step-by-step explanation:
Let the cost per vinyl album be 'a'
Let the yearly membership cost be 'b'
Given that,
4a + b = 35
7a + b = 57.5
9a + b = 72.5
We can take any 2 equations from the above,
(4a + b = 35 ) - (7a +b =57.5)
4a + b - 7a - b = 35 - 57.5
-3a = -22. 5
3a = 22.5
a = 7.5
The cost of each vinyl album is $7.5
4a + b = 35
4(7.5) + b = 35
30 + b = 35
b = 35 - 30
b = 5
The cost of the yearly membership is $5
The music store will charge $5 for a yearly membership.
Khloe ran around the track 7 times at the same rate of speed. It took her 21 minutes to run. Zachary took 4 minutes to run around the track once. Which student ran faster? Explain.
Zachary ran faster with 4 minutes per lap compared to Khloe's 3 minutes per lap.
To compare the speeds of Khloe and Zachary, we need to find their respective speeds in terms of minutes per lap.
Khloe ran around the track 7 times in 21 minutes, so her speed is [tex]\( \frac{21}{7} = 3 \)[/tex] minutes per lap.
Zachary took 4 minutes to run around the track once, so his speed is [tex]\( 4 \)[/tex] minutes per lap.
Comparing their speeds, Zachary's speed is faster at 4 minutes per lap, whereas Khloe's speed is 3 minutes per lap.
In summary, Zachary ran faster than Khloe because he completed each lap in 4 minutes compared to Khloe's 3 minutes per lap.

Which linear function represents the table? A) y = 7x − 7 B) y = 7x + 7 C) y = −7x + 7 D) y = −7x − 7
Answer:
Y = -7x+7
Step-by-step explanation:
(This takes a while)
A) Y = 7x - 7
B) Y = 7x + 7
C) Y = -7x + 7
D) Y = - 7x - 7
The asnwer is: C.
Because by distribution the numbers of [x], you will find that you will get [y]. And when you must do this with each of them in order to find out which is the right function.
(6,-35) -> Subsitute 6 into [x]:
Y = 7(6) - 7
Y = 42 - 7
Y = 35
This is wrong, because [y] is supposed to equal -35 and not 35. So A. is out.
B. is also positive, so that means you can't get a negative from it either, so that's out.
C. and D. are both negative, so its between these two.
Y = -7x + 7
Y = -7(6) +7
Y = -42 +7
Y = -35 <- Okay, so that's correct, now let's check D.
Y = -7(6) - 7
Y = -42 - 7
Y = -49 <- This answer is wrong, so your correct answer is C!
The best thing to do is distribute into each, it's quite a process, but it'll help you find out the answer!

How many games did they play
The number of games played is 9
Let the number of games played = g
Amount of bet per game = $2
Number of games won by Marty = 4
Number of games won by Wendy will be;
g - 4Amount won by Wendy = $10
This means ;
cost per bet × number of games won by Wendy = 10
2(g - 4) = 10
2g - 8 = 10
2g = 18
g = 9
Hence, They played 9 games.

0.3636...... = 4/11
B) __
0.36 = 0.366666.....
{After decimal point two digits are there but only one digit, 6 is repeated. so first multiply both sides of equation [x=0.366...] by 100 and mark it as equation (i) and then multiply both sides of the equation [x=0.366...] by 10 and mark it as (ii) equation }
x = 0.3666....
100x = 36.66666..... ---------- (i)
10x = 3.66666...... ---------(ii) {Now subtract (ii) from (i)}
90x = 33
x = 33/90
x = 11/30
0.36666..... = 11/30

In mathematics, the sign of a rational number is determined by the signs of the numerator and the denominator. If both the numerator and the denominator are of same sign (either positive or negative), the rational number is positive. If they have different signs (one positive, one negative), the rational number is negative.
Explanation:According to the rules of mathematics, the sign of a rational number is determined by the signs of the numerator and the denominator. If both are positive or both are negative, the resulting number is positive. If one is positive and the other is negative, the result is negative.

Answer:
the answer is the expression, 5n-3
Step-by-step explanation:
Answer:
The value of n is -3/2.
Step-by-step explanation:
In order to solve x, you have to use the Cross-Multiplication :
[tex] \frac{ - 3}{5n} = \frac{2}{5} [/tex]
[tex] - 3(5) = 2(5n)[/tex]
[tex] - 15 = 10n[/tex]

Step-by-step explanation:
a plane averaged 400 mph on a trip going east, but only 280 mph on the return trip. The total flying time in both directions was 8.5 hours. what was the one-way distance?
Answer:
1400 miles
Step-by-step explanation:
Speed is the time rate of change of distance. It is the ratio of distance to time and is given by the equation:
[tex]Speed(S) = \frac{distance(d)}{time(t)}\\ S=\frac{d}{t}[/tex]
plane averaged 400 mph on a trip going east, but only 280 mph on the return trip.
The time spent (t₁) in going east is given by:
[tex]S=\frac{d}{t_1}\\ t_1=\frac{d}{S} =\frac{d}{400mph}[/tex]
The time spent (t₂) in going east is given by:
[tex]S=\frac{d}{t_2}\\ t_2=\frac{d}{S} =\frac{d}{280mph}[/tex]
The total time (t) = t₁ + t₂
t = t₁ + t₂ = 8.5 hours
[tex]\frac{d}{400}+\frac{d}{280} =8.5\\280d+400d=952000\\680d=952000\\d=1400miles\\[/tex]
Therefore the one way distance is 1400 miles

Find the 4 term in the sequence
To find the fourth term in the sequence described by the expression c(n)=-7+6(-1), substitute n = 4 into the expression and simplify. the fourth term in the sequence is -13.
Explanation:To find the fourth term in the sequence given by c(n)=-7+6(-1), we need to substitute n = 4 into the expression and simplify.
First, substitute n = 4 into the expression:
c(4) = -7 + 6(-1)
Next, simplify the expression:
c(4) = -7 + (-6)
c(4) = -7 - 6
c(4) = -13

An entire commercial break is 3.6 minutes.
A different commercial break of the same length plays commercials half as long.
How many commercials will play during this break? Please help me
Assuming original commercials were 30 seconds long, during a 3.6-minute break, 7 commercials could fit. If they are half as long, or 15 seconds each, then 14 commercials could fit in the same time period.
The question is asking to calculate how many commercials will play during a commercial break that lasts 3.6 minutes if the commercials are half as long as the ones during the original break. To calculate this, you need to know the length of the original commercials. However, since this information was not provided in the question, let's for example assume that the original commercials were 30 seconds long each (a common commercial length).
If the original commercials were 30 seconds long, then during a 3.6-minute break (which converts to 216 seconds), you could fit in 216 / 30 = 7.2, which is not possible since you can't have a fraction of a commercial. So, you would normally have 7 commercials during the break.
If the new commercials are half as long, meaning they are 15 seconds each, then during the same 3.6-minute break, you could fit in 216 / 15 = 14.4, which again is not possible, so you would have 14 commercials play during the break since you can't have a fraction of a commercial.

We have in 2010, there were 1000 rabbits on an island. The population grows 8% every year.
Assume that the population in the year 2025 be [x]. We can write he annual growth multiplicative factor as 1.08. Now -
x = 1000(1.08)¹⁵
x = 3172
Therefore, the population of rabbits in the year 2025 will be 3172.
